Efforts to Sustain Traditional Methods of Crafting Rich Red Dye Persist in Central Mexico

A family located in the heartland of Mexico is steadfastly committed to the conservation of cochineal dye production, a vibrant, organic red pigment that, in terms of significance, followed only gold and silver as the most valuable resources discovered by the Spanish in Mexico post their 1521 invasion.

Historically, red and purple garments were emblematic of affluence and authority due to their scarcity and high cost. The indigenous method of extracting this pigment from insects provided the Spanish empire with an alternative source of the coveted red dye.

Cities of great historical and architectural value in Mexico, such as Oaxaca, owe much of their prosperity to the trade in cochineal dye, also referred to as carmine or “grana cochinilla” in Spanish. Esteemed by Spanish aristocrats, this dye was notably used to color the military uniforms of the British Empire’s Redcoats, until the advent of synthetic dyes in the 19th century.

The traditional method of acquiring this pigment is time-consuming, laborious, and meticulous. It is sourced from the crushed carcasses of diminutive female insects that contain carminic acid and subsist on nopal cactus plants.

Each of these insects, identified as Dactylopius coccus, must be cultivated until they reach the larvae stage and then placed on a purposely injured nopal cactus pad. Following this, the insect is left for several months to nourish itself and reach maturity.

Subsequently, each insect must be individually collected by hand, typically using a small brush, then sifted, cleansed, and sun-dried.

This technique for extracting the valuable pigment was initially devised by the Mixtecs of Oaxaca several centuries before the Spanish invasion. The pigment was a status symbol employed by indigenous Mexican nobility to color their garments, and it found widespread use in various art forms, including manuscript writing, ceramic decoration, and mural painting.

Mayeli Garcia and her family manage a greenhouse specializing in this labor-intensive, traditional production process in the village of San Francisco Tepeyacac, to the east of Mexico City. Rows of hundreds of nopal cactus pads are methodically arranged on elevated racks and covered in a white powdery substance, indicative of the insects nourishing themselves while simultaneously secreting a waxy protective layer.

“It requires a waiting period of three to four months for the insects to complete their life cycle, followed by the harvest,” Garcia explains. Constant vigilance over each cactus pad is obligatory. This practice is virtually unchanged from the methods used over the past three centuries to produce the finest red dye.

Synthetic dyes, more cost-effective and abundant, started to replace cochineal dye during the 19th century. Nevertheless, artisans in Oaxaca continued some level of production, particularly for use in traditional clothing and rugs.

Recent studies have indicated potential health risks associated with chemical dyes, especially when used as food colorings or cosmetic additives. Such concerns have rekindled interest in natural alternatives like cochineal dye.

Industrial-scale production remains unfeasible due to the limited quantities available. “We have experimented with automating some steps to lessen the manual labor, even inventing our own machinery,” said Garcia, although she admits their initial efforts were not entirely successful.

Garcia faces challenges in sustaining her livelihood from the approximately 100 kilograms (220 pounds) of cochineal dye she produces annually. She is exploring diversification strategies, including the production of other nopal-derived goods like soaps, creams, and jams. For supplemental income, her family continues to cultivate fresh vegetables.

Reducing the price of the dye is not a viable option, given the laborious nature of its production. “The costs associated with the labor make it prohibitive,” she states.

However, Garcia remains committed to preserving this unique ecological system designed to sustain these tiny insects. “There is a burgeoning movement towards revisiting traditional methods because they are intrinsically healthier,” she observes.
